Multistage gear-driven container for ejecting paste material

ABSTRACT

The present invention relates to a multistage gear-driven container for ejecting a paste material, which can control the ejection of paste by means of the operation of multistage drive gears so as to enable a stable ejection control, controls the ejection of the paste by means of the operation of the multistage drive gears, thereby exhibiting an effect of being able to perform more stable driving than the conventional lift screw, and forms an assembly-type structure having a removable container body, thereby providing an advantage of replacing only the container body storing paste products and enabling a lower driver to be reused.

TECHNICAL FIELD

The present invention relates to a container for ejecting a paste material, and more particularly, to a container for ejecting a paste material in which predetermined amounts of various kinds of paste materials are stored and preserved and the paste materials therein are ejectable to the outside to be used by a user as necessary.

BACKGROUND ART

Generally, a paste material refers to a material, such as toothpaste, an ointment, or a dye, which is present in a non-solidified state of a liquid when stored in a container and changes into a solidified state when exposed to the outside for a specific time.

A paste material used in everyday life is usually stored in a soft flexible tube and may be ejected to the outside by applying an external force to compress the tube.

The paste material stored in a tube made of such a flexible material is often discarded in a state in which a residual paste material is present in the tube because it is not easy to completely compress the tube.

In order to solve such a problem, the present applicant has developed the “Container structure for paste extracting” disclosed in Korean Patent Application No. 10-2013-15443 filed on Feb. 13, 2013.

That is, a technical structure according to the above-described conventional technology includes an inner diaphragm vertically formed and configured to isolate two or more kinds of paste materials stored therein from each other, a container body in which an ejecting port is formed at an upper portion thereof such that the paste materials may be ejected, a plurality of pressing plates included in the container body to push the paste materials stored in the container body upward, a lifting and lowering screw screw-coupled to the pressing plates to lift and lower the pressing plates, a driven gear integrally formed with a lower end of the lifting and lowering screw, and a drive housing having a driving unit configured to transmit a rotational force to the driven gear.

However, in the above-described conventional technology, since the pressing plate is lifted or lowered according to rotation of the lifting and lowering screw in a state in which the pressing plate is screw-coupled to the lifting and lowering screw, there is a problem in that a malfunction occurs when a thread formed on the pressing plate becomes dull or is deformed.

DISCLOSURE Technical Problem

The present invention is directed to providing a container for ejecting a paste having a structure in which a lifting and lowering adjustment of a pressing plate is performed by a multistage gear which does not use a screw method, and thus a paste container is more stably used.

In addition, the present invention is also directed to providing an assembly-type structure from which a container body configured to store a paste material may be separated, and in which only the container body may be replaced after use so that a container for ejecting a paste may be reused.

Technical Solution

One aspect of the present invention provides a multistage gear-driven container for ejecting a paste including: a container body having a partition wall which divides an inner space into a plurality of spaces; a main body pressing plate lifted and lowered in the container body; a gear driver detachably coupled to a lower portion of the container body; a drive gear formed in the gear driver; a driven gear configured to receive a rotational force from the drive gear; a lower pressing plate formed above the driven gear and configured to lift the main body pressing plate; a multistage lifting and lowering gear in which a plurality of lifting and lowering gears having different diameters are connected by screw-coupling to receive the rotational force from the driven gear and to lift and lower the lower pressing plate; an inner housing configured to support the driven gear in the gear driver; and a motor driver installed under the gear driver and including a driving motor configured to transmit a driving force to the drive gear formed in the gear driver.

A male screw may be formed on an outer surface of a lower portion of the container body and a female screw corresponding to the male screw may be formed in an inner circumferential surface of an upper portion of the gear driver such that a detachable structure may be formed.

The lifting and lowering gears included in the multistage lifting and lowering gear may have a structure in which diameters of the lifting and lowering gears may gradually increase from a bottom lifting and lowering gear located at a lower portion in the multistage lifting and lowering gear to a top lifting and lowering gear located at an upper portion therein, an outer screw thread may be formed on an outer wall surface of each of the lifting and lowering gears, an inner screw thread may be formed on an inner wall surface of only an upper end portion of each of the lifting and lowering gears, and a stopper configured to prevent deviation may be formed at a lower portion of each of the lifting and lowering gears.

Advantageous Effects

According to the present invention, since an adjustment of ejecting paste is performed by an operation of a multistage drive gear in a container for ejecting a paste, there is an effect in that the container for ejecting a paste can be more stably driven than a conventional lifting and lowering screw.

In addition, since an assembly-type structure from which a container body can be separated is provided, there is an effect in that a container body in which a paste product is stored can be replaced and a driver located under the container body can be reused.

MODES OF THE INVENTION

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a structure of a container for ejecting a paste material according to one embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

In the container for ejecting a paste according to the present invention, a gear driver 30 is assembled to a lower portion of a container body 10, and a motor driver 40 including a driving motor 41 is coupled to a lower portion of the gear driver 30.

In the above structure, a partition wall 11 is vertically formed in the container body 10 such that an inner space thereof is divided into a plurality of spaces, that is two or more spaces, and different kinds and compositions of paste materials are individually stored therein, and a main body pressing plate 20 is formed in each of the divided spaces to be liftable and lowerable. Reference numeral 12, which is not described, denotes an ejecting port through which the paste materials are ejected.

Meanwhile, the gear driver 30 has a structure in which a female screw 36 is formed in an inner circumferential surface thereof to be detachably screw-coupled to a male screw 16 formed on a lower outside surface of the container body 10, a drive gear 31 configured to receive a driving force from the driving motor 41 is formed at a center of an interior of the gear driver 30, a driven gear 32 configured to receive a rotational force from the drive gear 31 is formed at each of both sides of the drive gear 31, a lower pressing plate 33 configured to lift the main body pressing plate 20 is formed above the driven gear 32, a multistage lifting and lowering gear 34 in which a plurality of gears having different diameters are connected by screw-engagement is formed in the driven gear 32 to receive a rotational force from the driven gear 32 and to lift and lower the lower pressing plate 33, and an inner housing 35 configured to support the driven gear 32 is formed in the gear driver 30.

Particularly, lifting and lowering gears included in the multistage lifting and lowering gear 34 have a structure in which diameters d of the lifting and lowering gears gradually increase from a bottom lifting and lowering gear located at a lower portion in the multistage lifting and lowering gear 34 to a top lifting and lowering gear located at an upper portion therein as illustrated in FIGS. 2 to 4, an outer screw thread 34 a is formed on an outer wall surface of each of the lifting and lowering gears, an inner screw thread 34 b is formed on an inner wall surface of only an upper end portion of each of the lifting and lowering gears, a stopper 34 c configured to prevent deviation are formed at a lower portion of each of the lifting and lowering gears, and a lower screw thread 32′ is formed at an inner wall surface of an upper portion of the driven gear 32 to be screw-coupled to a gear located at an outermost side in the multistage lifting and lowering gear 34.

In addition, it can be seen that a protrusion insertion groove 34 a′ into which a lower protrusion 33′, which protrudes from a center of a lower surface of the lower pressing plate 33, may be fixedly inserted is formed in a lifting and lowering gear located at a center of the multistage lifting and lowering gear 34.

In the present invention, as the container body 10, the lower pressing plate 33, and the main body pressing plate 20 are formed in rectangular shapes, it is preferable to prevent rotation of the main body pressing plate 20.

In addition, it is preferable to form an operating switch (not shown) configured to transmit an operating signal to the driving motor 41 on an outer wall surface of the motor driver 40, and such an operating switch may be formed in various forms, for example, a lifting switch and a lowering switch are separately formed, or one operating switch is formed such that the one operating switch is raised to perform lifting and is lowered to perform lowering.

Operating effects according to a use of the container for ejecting a paste having the above-described structure will be described.

In a case in which a user wants to eject a paste material in a state in which two or more kinds of paste materials are isolated from each other by the partition wall 11 and stored in the container body 10, when the user pushes an operating switch (not shown), power is applied to the driving motor 41, the driving motor 41 is driven, the drive gear 31 rotates in a forward direction to rotate the driven gear 32 located at either side thereof, the main body pressing plate 20 is accordingly lifted due to a lifting movement of the multistage lifting and lowering gear 34, and thus the paste material is ejected through the ejecting port 12.

That is, when the drive gear 31 rotates in the forward direction, the driven gear 32 located at either side thereof is rotated and, at this time, the multistage lifting and lowering gear 34 in which the lifting and lowering gears are stacked in the driven gear 32 is gradually lifted due to gear actions therebetween, and thus the lower pressing plate 33 pushes and lifts the main body pressing plate 20.

This is because rotation of the lifting and lowering gear located at the center of the multistage lifting and lowering gear 34 is prevented by the center lifting and lowering gear being fixed to the lower pressing plate 33 so that the lifting and lowering gear located at the center of the multistage lifting and lowering gear 34 rotates due to engagement actions between the other lifting and lowering gears included in the multistage lifting and lowering gear 34.

At this time, lifting is sequentially performed from a lifting and lowering gear which is located at an outermost side among four lifting and lowering gears included in the multistage lifting and lowering gear 34 and to which a rotational force from the driven gear 32 is primarily transmitted.

Particularly, since the outer screw thread 34 a is engaged with the inner screw thread 34 b in the multistage lifting and lowering gear 34, a lifting and lowering gear located at an upper portion in the multistage lifting and lowering gear 34 is lifted by a rotation action of a lifting and lowering gear located at a lower portion therein, and the lifting action is limited to within a predetermined height by the stoppers 34 c.

In addition, it can be seen that a lifting and lowering gear having the largest diameter in the multistage lifting and lowering gear 34 is lifted due to an action with the lower screw thread 32′ of the driven gear 32.

Accordingly, it may be seen that a set amount of paste material may be ejected due to a lifting operation of the multistage lifting and lowering gear 34 which acts due to a screw engagement between the lifting and lowering gears in a state in which the lifting and lowering gears are stacked in a multistage structure.

In addition, in a case in which the user wants to stop ejecting the paste material, when the user releases user's finger from the operating switch, the lifting of the multistage lifting and lowering gear 34 stops, the ejection of the paste material stops, and in a case in which the paste material is excessively ejected, when the user pushes a reverse switch (not shown) to drive the drive gear 31 in a reverse direction, the driven gear 32 rotates in an opposite direction, the multistage lifting and lowering gear 34 is lowered, and thus the ejected paste material may be reintroduced into the container body 10.

Meanwhile, in the container for ejecting a paste according to the present invention, since the container body 10 and the gear driver 30 are assembled by the male screw 16 and the female screw 36, when the ejection of a paste material is completed, the container body 10 may be separated from the container, a new container body 10 may be assembled to the container to be used, and thus there is an advantage in that the container may be reused.

In addition, FIGS. 7 and 8 are views illustrating a cross-sectional structure of a multistage lifting and lowering gear according to another embodiment of the present invention, and it can be seen that an elastic spring 50 configured to elastically support lifting and lowering is provided in a multistage lifting and lowering gear 34, an insertion groove 51 into which an upper end of the elastic spring 50 is inserted to be supported is formed in a lifting and lowering gear located at a center of the multistage lifting and lowering gear 34, a guide plate 52 in a circular plate form is connected at a lower end of the elastic spring 50, and a seating groove 53 on which the guide plate 52 may be seated is formed in a bottom surface of a driven gear 32.

When such a structure is formed, since an elastic force of the elastic spring 50 is applied to the multistage lifting and lowering gear 34, a lifting pressure may be more effectively applied to the main body pressing plate 20, and thus lowering of the lifting and lowering gear 34 may be prevented during operation.

In addition, it can be seen that the elastic spring 50 may be more stably supported by the guide plate 52 and the seating groove 53.

In addition, although specific embodiments according to the present invention are described and illustrated, it should be clear that the structure of the container for ejecting a paste according to the present invention may be variously modified and made by those skilled in the art.

For example, although the multistage lifting and lowering gear 34 is provided with five stages in the drawings, the multistage lifting and lowering gear 34 may be provided with three stages or six or more stages as necessary.

In addition, as amounts of transmitted rotational force of left and right driven gears 32 are adjusted or as two drive gears 31 are individually installed for the left and right driven gears 32 and a driving switch is installed for each of the driven gears 32, ejecting amounts of left and right paste materials may be adjusted to be different.

In addition, as a onetime driving amount of the drive gear 31 is set in advance to eject a preset amount of a paste material by rotating the drive gear 31 by a preset number of revolutions when a user pushes an operating switch once, an excessive ejection of the paste material may be prevented, and thus children or the elderly may easily use the container.
